Ftir 1600

The structural nature of the T-NPs was evaluated using XRD (Perkin-Elmer FTIR-1600, Massachusetts, USA). The samples were run between 20 and 70 2θ [28 (link)]. The particle size of T-NPs was also calculated, using the Debye-Scherrer equation given below.
$\text{Debye-Scherrer equation}=\mathsf{\tau }=\frac{K\lambda }{\mathsf{\beta }\cos \theta }$

Nano curcu were characterized by FTIR (Perkin-Elmer FTIR-1600, USA) mixing dried powder of nanoparticles with KBr. Spectra were taken in the range of 500–2000 cm⁻¹ at a resolution of 4 cm⁻¹. The data of FTIR reveal information about functional groups which are present in the Nano curcu.

AgNPs were characterized according to methods used by Saied et al. [34 (link)]. A reaction mix ranging from light yellow to brownish was formed after 24 h. The formation of AgNPs was thought to be indicated by this color change, in which the color shift of control was not seen as compared to the sample. The results were confirmed using conventional characterization methods, such as a UV–visible spectrophotometer (scanning spectra 10⁹ range from 300 to 700 nm, Shimadzu UV-1700, Kyoto, Japan). The morphology of AgNPs was examined using transmission electron microscopy (JEOL 1010 TEM, Japan). The functional groups involved in reducing, capping, and stabilization of AgNPs were studied using Fourier transform infrared spectroscopy (FTIR) (Perkin-Elmer FTIR-1600, USA) by following the standard operating protocol, and the spectral bands of prepared (crystallized form) AgNPs were determined with 400–4000 cm⁻¹. X-ray diffraction (XRD) (Shimadzu LabX XRD-6000) with a Cu-Kα X-ray source (λ = 1.5418 Å) analysis was used to evaluate the crystallite nature of AgNPs. The average particle size and size distribution of AgNPs in colloidal solutions were determined by dynamic light scattering (DLS) (The Nicomp ZLS Z 3000, USA).
